Longtermism is the schism, and it is a schism of the ordinary kind: the same premises, followed further, producing a different religion. If future people count equally and there could be enormous numbers of them, then reducing the probability of human extinction by a fraction of a per cent outweighs any number of malaria nets, and the movement's money and talent should move accordingly — which is what happened, visibly, between roughly 2015 and 2022. The global-health wing regards this as a reductio: a framework that started by insisting on evidence has arrived at unfalsifiable estimates about centuries nobody can observe. The longtermist wing regards the objection as a failure of nerve. Marked contested because the disagreement is public, unresolved, and determines where hundreds of millions of dollars go.
